如何使AlertDialog消失? [英] How to make an AlertDialog disappear?

问题描述

我正在尝试将Twitter与我的应用程序集成在一起，我想添加一个AlertDialog，该对话框将在用户按下按钮后显示，并且该AlertDialog将询问用户是否要发布推文(所有推文都相同)用户，例如促销推文).我的问题是，是否有任何方法可以使警报对话框在片刻之后(例如5秒钟)消失.

I am trying to integrate Twitter with my application and I thought to add an AlertDialog which will appear after users press a button and this AlertDialog will ask the users if they want to post a tweet(The tweet will be the same for all users, like a promo tweet). My question is if there is any way to make the Alert Dialog disappear after a few moments, like 5 seconds.

我发现了此，但我不确定它是如何工作的.我将不胜感激.

I found this but I am not completely sure how it works. I would appreciate any help.

推荐答案

声明您的Handler，将在一段时间后关闭对话框，并声明将暂停当前线程并保持对话框一定数量的线程.时间.在线程的Runnable中，使语句休眠一段时间，例如Thread.sleep(5000);，然后将Handler对象用于sendMessage()；在Handler onHandleMessage()方法中，只需执行dialog.dissmiss();操作，在要保留对话框的位置，然后使用myThread.start();启动线程.每次在需要/需要的地方注意线程的实例化.

Declare your Handler that will deal to dismiss the dialog after some time, and declare thread that will pause the current thread and keep dialog for a some amount of time. In the Runnable of the thread make a statement that will sleep the thread for a some time, e.g Thread.sleep(5000); then use the Handler object to sendMessage();, in the Handler onHandleMessage() method just do dialog.dissmiss(); After some operation, at point where you want keep the dialog, and start the thread using myThread.start();. Mind the instantiation of the thread each time when/where you need.
